74AHCT125-Q100
Quad buffer/line driver; 3-state
Rev. 1 — 5 June 2012
Product data sheet
1. General description
The 74AHC125-Q100; 74AHCT125-Q100 is a high-speed Si-gate CMOS device and is
pin compatible with Low-power Schottky TTL (LSTTL). They are specified in compliance
with JEDEC standard JESD7-A.
The 74AHC125-Q100; 74AHCT125-Q100 provides four non-inverting buffer/line drivers
with 3-state outputs. The 3-state outputs (nY) are controlled by the output enable input
(nOE). A HIGH at nOE causes the outputs to assume a high-impedance OFF-state.
The 74AHC125-Q100; 74AHCT125-Q100 is identical to the 74AHC126-Q100;
74AHCT126-Q100 but has active LOW enable inputs.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
2. Features and benefits

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.
